ACCELERATOR.

Patented Feb. 27, 1917.

Application filed November 30, 1914." Serial No.-'8'74,803.-

To'aZZ whom it may concern:

Be it known that we, EMERY H. MU'IZ and VERGIL 0. Mom, citizens of the United States, residing at Sacred Heart, in the county of Renville and State of Minnesota, have invented certain new and useful Improvements in Accelerators, of which the following is a specification,

This invention relates to an accelerator for automobiles, and particularly concerns an accelerator adapted to be used in connection with that type of automobile known as a Ford from the name of its manufacturer. I 1

As a principal object, this invention contemplates the introduction of an accelerator adapted to be controlled either by the foot or by the hand of the operator in order to increase the speed of the engine by an increased admission of the explosive mixture thereinto from the carbureter. V

A further object is toadapt the means for footor hand control of this accelerating device for independent operation upon a single rotatable element so that operation of the foot control will not actuate the manual control.

An object of equal importance with the foregoing is to so construct adevice ofthe character described and with such regard to proportion, number and arrangement of parts as to render the same capable of being cheaply manufactured as well as durable and efficient in operation.

The above and additional objects which will become apparent as this explanatory description proceeds, are accomplished by such means as are illustrated in the accompanying drawings,'described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part inthis application. With reference to the drawings, wherein there is illustrated the preferred embodiment of this invention as it is reduced to practice, and throughout the several views of which like characters of reference designate similar parts Figure 1' is an elevational view of the steering mechanism of a Ford automobile, parts of the dash being shown in section,

Fig. 2 is a fragmentary plan of the matter disclosed in Fig. 1,

Fi 3 is an enlarged elevation of the automobile element doubly controlled,

, Fig. 1 is a vertical section taken through the matter disclosed in Fig. 3, and

Figs. 5, 6 and 7 are transverse views taken respectively on the planes indicated by the lines 66 and 77 of Fig. 3.

Upon reference to the drawings, there will be seen illustrated the dash 10 of an automobile body which is provided with the usual flooring 11 and foot board 12, in the latter of which is arranged the usual pedal control plate 13.. Extending through the dash 10 at an angle thereto are the control rods 14 and 15 for the carbureter and the spark of the engine respectively, such rods being grouped together with the steering rod 16in thetubular casing 17 which extends from the dash where it is supported as indicated at 18, diagonally upward to rotatably support. the steering wheel 19 secured to the rod 16, as well as supporting the various control levers 20 over respective rods 14: and 15. A toothed locking segment is preferably employed to insure position of the controls 20 at thei1."adjusted point.

To fulfil the preceding objects, the in- Yention consists in a carburetor controlling mechanism comprising two separately operable devices, the one controlling the gas inlet for the carbureter through its entire ,range of adjustment, and the other controlling merely an adjustment beyond the point at which the first controlling device is set, that is, more fuel may be admitted through the inlet by operation ofthe second controlling device, but the inlet cannot 'be closed thereby beyond the point determined by the setting of thefirst controlling device.

It is with the control ofthe carbureter, that this invention is primarily concerned and for this reason the rod 14 only is fully illustrated. As shown in Figs, '3 and 1- this rod extends downwardly to be surrounded loosely by a cylindrical casing 21, and to carry the bracket 22' spaced from the casing 21 and slightly thereabove on the rod 14. As shown in Fig. 6, the bracket includes a central cylindrical gripping portion 23 to surround the rod 1 1 being provided with the radial slot 24 whereby a certain accommodation of the gripping movement upon the rod 14 is permitted, this movement being assured by the clamping strap 25 provided with the extending ears 26 through which is projected the fastening means 27 in such a manner as to removably secure this bracket upon the rod. Formed integrally upon the gripping portion 23 and extending laterally therefrom is the clutch extension 28 as is clearly shown in Figs. 3 and 5, being thus obviously adapted for movement with the rod 1 1.

A similar clutch extension 29 is formed on the loosely mounted casing for engagement with the extension 28 in the manner illustrated. This casing 21 includes similarly to the bracket 22 a cylindrical body portion loosely surrounding the rod 14, reference being now had to Fig. 7 and also provided with av longitudinal radial slot 30 in which there is arranged the rib 31 of like length as the casing and provided with in tegral upstanding ears 32 which are adapted to be embraced by straps 33 similar to the mentioned straps 35 and also provided with securing means 27. Upon this rotatable casing'are provided the angular extensions or 'arms 34 which project out therefrom at right angles to each other. Fromthe lowermost of these arms is led any suitable connection 35 to the gas inlet of the carbureter so that rotation of the casing may be depended uponto control the amount of explosive mixture admitted from the carbureter to the intake manifold of the engine.

' It now remains to describe the particular adaptation of a foot control for this casing and consequently the carburetor. A central portion 36 of a rod is mounted. in suitable brackets 37 upon the underside of the illclined foot board and formed upon one extremity with the L-shaped extension 38 adapted to project upwardly through a slot 38 provided in the foot board and of sullicient length to accommodate a rotational movement of the bar 36. This latter upon its opposite extremity is formed with the right angular extension 39 extending clownwardly from the portion 36 and formed with the eye 40 between which and the uppermost arm 34 of the casing is established a loose link connection 41 all as clearly shown in Figs. "1 and 2. A suitable resilient means 42 is interposed between the lower edge of the dash 10 and the center of the arm 39, such resilient means being contractile to normally maintain the rod portion 36 and its adjuncts in the position illustrated.

When operating this accelerator to increase the speed of a car recourse may be had to either the foot pedal 38 or the lever 20. In the first case a forward push upon the pedal 38 results in a backward movement of the arm 39 which through its loose link connection causes a turn of the casing 21 in a clockwise direction, consequently exerting the desired pull upon the carbureter connection 35. A similar effect is had by rotation of the rod 14 causing the clutch extensions 28 and 29 to engage and operate the casing and the rod 25 in a like manner.

It will be seen that movement of the pedal is independent of all movement of the rod 14 and consequently of the lever 20 and that such movement is resiliently resisted bythe spring 42. On the other hand movement of the control lever 20 also moves the pedal 31 since the link 4:1 is a rigid connection and it is thus permitted that the spring 42 also resilientlyresist this movement thus obviating the necessity for an additional spring or springs.

It should also be apparent that the operator of the automobile may set the manual lever to control the inlet of fuel to the carbureter to the desired degree and may thereafter momentarily accelerate the speed of the car by depressing the foot pedal which will open the inlet still farther. The spring means, however, will always return the pedal to that position determined by the previous adjustment of the manual control, and unless the latter is secured by its customary locking segment will also return it to the point where the carbureter throttle is entirely closed off.

What is claimed is 1. In an accelerator, a rod capable of being manually turned on itslongitudinal axis, a casing loosely mounted for rotation upon said rod, means for connecting the same to a carbureter, a bracket or collar fixed to said rod and spaced a short distance from said casing, a pedal, direct connections between said pedal and said casing for rotating the casing upon depression of the pedal independently of said rod, and cooperating means on said casing and said bracket to cause the rotation of said casing when said rod is manually turned.

2. In an accelerator, a'rod capable of being manually turned about its longitudinal axis, a casing loosely mounted upon said rod and having arms projecting at. an angle thereto and to each other, one of said arms adapted to be connected to a carbureter, a hand operating lever, connections therebotween and the casing for rotating the casing, means rigidly mounted on said rod adapted to engage said casing during a portion of its rotation, and means on said rod for manu ally turning the same.

3. In an accelerator for an automobile, a rod extending downwardly at an inclination to the dash of said automobile, a casing loosely mounted on the lower end of said rod, an arm projecting at right angles from the lower end of said casing, a second arm at the upper end of said casing and projecting at right angles thereto and to the first named arm, an upwardly projecting lug on the top of said casing, a collar rigidly mounted on said rod adjacent the upper end of said casing and having a projection thereon to engage under certain conditions with the lug of said casing, manual means for rotating Copies of this patent may be obtained for five cents each, by addressing the In testlmony whereof we aflix our signa- 15 tures in presence of two witnesses.
